lyric engine patches, solves
- pixeled/transparent fonts bug - some lines were erroneously marked active or disabled - state was not initialized correctly - negative gap problem (TLyricLine.Start was of type cardinal) - some more lyrics bugs git-svn-id: svn://svn.code.sf.net/p/ultrastardx/svn/trunk@1211 b956fd51-792f-4845-bead-9b4dfca2ff2c
